Embodiment Construction

[0012]A detailed description of one or more embodiments of the disclosed apparatus and method are presented herein by way of exemplification and not limitation with reference to the Figures.

[0013]Embodiments of a diverting system disclosed herein allow a first tubular to run fully within a main of a second tubular and subsequently to run the first tubular into a plurality of lateral tubulars extending from the second tubular without having to withdraw the first tubular from the second tubular prior to doing so. In a downhole operation, for example, an operator could run a drillstring down a main wellbore past any number of laterals extending from the main wellbore. The operator could then sequentially run the drillstring into each of the laterals in succession starting with the lowest lateral and ending with the highest lateral, all during a single run of the drillstring. Optionally, the operator could choose to skip running the drillstring into any one or more of the laterals durin...

Abstract

A diverting tool includes a ramp repositionable from a first position to a second position, a biasing member in operable communication with the ramp biasing the ramp toward the second position, and a tubular in operable communication with the ramp and the biasing member. The tubular prevents repositioning of the ramp when longitudinally overlapping with the ramp and allows repositioning of the ramp when not longitudinally overlapping with the ramp.

Description

BACKGROUND[0001]Industries involving tubular systems such as the downhole completion industry, for example, sometimes have a need to run a tubular, such as a drillstring, within a main tubular, such as a borehole. Such systems sometimes have offshoots from the main tubular often referred to as laterals. At times, operators of these systems have a need to run into one or more of the laterals. Typical systems and methods to do such an operation require the tubular to be fully withdrawn from the main before running back into one of the laterals. Having to withdraw the tubular from the main before running it into a lateral causes an operator to incur economic penalties associated with added labor and lost time. Methods and systems that lessen such economic penalties are always well received by system operators.BRIEF DESCRIPTION[0002]Disclosed herein is a diverting tool. The diverting tool includes, a ramp repositionable from a first position to a second position, a biasing member in ope...
